The use of space is considered as a structural part of a musical composition. The developments in the spatial audio reproduction technology has changed the way we perceive the sound. So, it is inevitable to put emphasis on ”composing space” in parallel with ”composing sound”. This thesis is aimed at composers who seek how recent spatial audio reproduction technology contributes to the compositional process. In order to grasp the idea behind ”composing space” by using recent spatial audio reproduction methods; the importance of space in history, pioneering technological innovations in audio technology, brief technical explanations of the spatialisation techniques and analysis of three pieces in the context of spatial audio reproduction technologies will be presented and discussed throughout the text.
